Used Keeley 4 Knob Compressor Effect Pedal

This used Keeley 4 Knob Compressor is in excellent condition and delivers studio-smooth sustain and punchy leveling for electric guitar or bass. Simple, musical controls for Sustain, Level, Attack, and Clipping let you dial in everything from subtle sparkle to rich, squashed compression with low noise and great note clarity. Built in a rugged metal enclosure with true bypass switching, it runs on a standard 9V DC center-negative supply and fits easily on any pedalboard.
